I'll take a look. It's an interesting coincidence that most of the WILLRELE violations were in the name creation and name management vops. Just about every place I corrected a vrele/vput was a also a nameifree() screaming to be moved/corrected too. I've done the dvp's for 5 name creation ops, vop_create, vop_mkdir, vop_symlink, vop_link, and vop_mknod; and 1 of 3 name modification ops, vop_rmdir. I think I'll press on and do the other 2, and vop_remove and vop_rename.
